"I was talking to him several days ago, inquiring as to why he had stopped writing for Emirati newspaper Al-Bayan, for which he had written weekly for nearly 25 years," Qalash posted on social media.
The Journalists Syndicate previously dismissed two of its members for holding meetings with Israelis, despite Egypt being the first Arab country to establish ties with Israel.
The UAE and Bahrain signed an agreement to establish full diplomatic ties with Israel earlier this month at the White House.
The Trump administration has made Israel-Arab normalisation a key focus of its Middle East foreign policy, claiming them to be "peace deals".
The two Gulf countries broke decades of consensus among Arab states that there would be no relations with Israel until Palestinian statehood had been assured.
